Thousands of people froze to death in the winter in the Soviet Union. Why don't Germans burn trees to keep warm?

In fact, I think the Germans will definitely think of this. So in the face of the Soviet Union with a large area of virgin forest. Why don't these German soldiers cut down forests and make a fire to keep warm?

194 1 in autumn, Moscow ushered in a long autumn rain season of six months, and the transportation system of the Soviet Union itself was relatively backward. During the long rainy season, the traffic became muddy. Such a bad battlefield environment has seriously slowed down the speed of German attack and the supply of logistics, and with the arrival of winter. The ill-prepared German soldiers came up with another question: How to resist the cold winter and low temperature? Many German soldiers still wear thin military uniforms because of difficulties in logistics supply and thoughtless initial consideration.

Not to mention how difficult it is to cut down forests to keep warm. Making a fire to keep warm can only solve the temporary problems during the armistice period, but not the problems on the battlefield. German soldiers at the front can't be allowed to ignite a raging fire while fighting. In other words, it is impossible to solve the fundamental problem of German soldiers' lack of materials in winter by logging and making a fire to keep warm. The delay of Barbarossa plan, the bad natural weather outside Moscow, the contempt of Nazi Germany's high-level officials for Moscow and the desperate resistance of the Soviet Red Army led to the failure of Nazi Germany in defending Moscow. The reason why the Barbarossa Plan was postponed for more than a month was that Italy led by Mussolini, an ally of Nazi Germany, suffered setbacks in the southern battlefield. So Hitler had to help Italy temporarily, thus delaying the time and plan to attack the Soviet Union.

In this cold winter, the Germans are wearing thin military uniforms. How can they defeat the fully armed Soviet Red Army? This may also be an act of god. 194 1 is extremely cold in winter. Evil will never prevail over justice!
